Firefighters say a large commercial fire in Darnley Street in Old Trafford has been brought under control.
Six crews and two antenna devices remain on site to tackle the blaze and road closures remain in place.
Two gas bottles have been found in the building and fire fighters are also working to keep them cool.
Approximately 45 people had to leave as a precaution in nearby premises and the Trafford Council worked with them.
It is not believed that the fire is suspect, but an investigation will take place in due course.
